CARrPLATFOlR-M.

Patented Mar. 5, 1912.

Original application filed September 8, 1908, Serial No. 451,795.Divided and this application filed June 21,

To all whom it may concern:

Be it known that I, ERNEST H. SoriMnrr,

' of Cleveland, in the county of Cuyahoga and State of Ohio, haveinvented a new and useful Improvement in Car-Platforms, of which thefollowing is a full, clear, and exact description, reference being badto the accompanying drawings, forming part of this specification, inwhich- Figure 1 is a plan view partly in section, illustrating myinvention; Fig. 2 is a longitudinal section thereof; Fig. 3 is a partialside elevation partly in section, of the platform casting.

In the drawings, 1 is the coupler head, having a shank 2, affixed to arear extension 3 which is extended to and is pivotally connected withthe draft rigging 4, the draft rigging being mounted between the carsills so as to be adapted for longitudinal motion in buffing and draft,but being held from lateral swinging motion with the coupler.

6 is the transverse member of the buffer, having a shank 7, which isdivided or forked longitudinally and is attached by vertical bolts 8 toa buffer shank extension 9, which extends rearwardly in line with thebuffer shank.

10 is the buffer yoke, preferably made in the form of a casting which,at its forward portion as shown in section in Fig. 2, is preferably of abox shape and at its rear portion is of loop or U-shape having side armsonly. The yoke is fitted around the buffer shank extension 9 andprojects rearwardly therefrom and in line therewith so as to containwithin its arms the buffer spring, which preferably consists of outerand inner coils 11, 11.

14 is the end sill of the platform which acts as a carry-iron for thebuffer, passing for this purpose between the arms of its shank 7 andbeing curved or,segmental in form so as to present a forward curvedbuffing face for the transverse member 6 of the buffer when it reachesthe rear limit of its buffing action. The buffing strains are normallytransmitted to a divided segment 15, the members of which are paralleland separated by an intermediate space through which the buffer shankextension and the yoke pass. These members of the divided Serial No.503,421.

segment are preferably made integral with a platform casting 16, whichconstitutes a part of the platform of the car. The parts 14 and 15 maybe integralwith one another and with cheek-plates 17, and bolster 17',making an integral casting of the bolster and all the parts of the carframe in front of the bolster.

When the bufling strains are received by the transverse member 6 of thebuffer they are transmitted through its shank 7 and the shank extension9 to the springs 11, 11. These springs are held from rearward movementby the yoke 10 which in turn is held by engagement of its front end 10'with the divided segment 15, so that the spring is compressed andresists yieldingly the rearward motion of the buffer shank.

By reason of the several points of engagement of the buffer with thecoupler, the buffer and coupler will swing laterally together, but asabove explained, the coupler is capable of forward motion independentlyof the buffer and during such forward motion the buffer follows the sameby reason of the expansive action of its spring. By connecting thecoupler to the truck with guiding connections, shown in Fig. 1, thecoupler and buffer are guided radially to the approximate center of thecar track at all times and are thus maintained in proper position forcoupling.

I claim:

1. A car platform for radial draft gear having a bufling segment 15, andan end carry iron and bolster all integrally attached thereto.

2. A car platform for radial draft gear having a horizontally dividedbuffing segment integral therewith in the rear of the front face of theplatform.

3. A platform for passenger cars having radial draft gears, saidplatform comprising an integral structure having downwardly extendingwebs forming forwardly diverging draft sills, the front end sill of thestructure having carry-iron forming portions for a swinging buffer, andthe structure having a divided bufl'er segment back of the end sill;substantially as described.

4. A platform for passenger cars having radial draft gears, the platformcomprising In testimony whereof, I have hereunto set an integralstructure having its end sill my hand. formed With a carry-iron portionbelow its platforn1-for1ning portion, the front end of ERNEST SCHMIDTthe end sill being curved, and the structure Witnesses:

having a divided bufler segment back of the HARRY E. ORR,

end sill; substantially as described. FLORENCE M. MILLER.
